Ive posted before and I was doing great with 4 months of smoke free. Tonight a bad episode of shortness of breath. How much longer til its gone? Doctors said no copd and no asthma but this is driving me nuts. Ekg and blood work and xrays and ct scans all normal. Is this even worth it? Is it just from anxiety as since ive quit I take a low dose from time to time. The annoying part I even get short of breath sometimes just from talking for a period of time and have dizzy spells. Im a fit person but haven't exercised since I quit. Smoked ten years a pack a day started at 26. They say this isn't long and I should be ok from the smoking but man why the SOB like someone stepping on my chest and just from talking I have to catch up. Some words of encouragement as im losing my mind here and tired of feeling like shit.
